r Be it known thatI, CARL 'GA RiELsorI, a citizen of the United States," and. resident of. Syracn se county of Onondaga, State of New Yorlg' have. invented certain new .and f flusefuh Improvements in Platen Position Indicators, of which the following is a j specification. IT The present invention relates to animproveinent .in typewriting machines" and particularly to an i attachment which may be; termed a platen position indicator and which isparticularly"intended for use in so called condensed billing and other special work; i y Y i The ob'ectiof the invention is to provide a simple attachment for a :typewriting inafchine by means of which an operator may, without I special care or attention,- properly positionwthe first line of writing on each tance from the upper edge of the sheet. The attachment; as above noted,'is especially applicable for use lincondensed 'billing'work or the writing of addresses on circular let- 13ers" e i i o I v .;In the accompanying drawings: Figure 1 yis a plan View [Di a portionof the carriage and. platen of atypewriting machine having an? embodiment of the invention applied thereto; Fig. 2 'is an end elevation; Fig. isiga: plan view of some of the partssho-wn fig. 1, the parts being in. a (lifi'ercnt potion from that illustrated in Figs. 1 and t the} improved attachment.

On ajstncl 7 carried *hy the pointer ,8 are mountedtwo gears 6', which respectively mesh with the aforesaid segmental rack and a pinion securei'l re ns-platen shaft 2. -The pinions (ia-re' frictionally,connected so that while the pointer S ihay'be caused to move with the platen astlie lattcr is rotated the pointer may he hell'stationary without interfering with the turning niovement of the platen. i :j

Loosely mounted on-the huh Tof the platen 1 is aseconrl'arin or pointer li which is provided adjacent its free end with "a pin or stud 13 adapted to engageany'pne of a series 'o'f soeket's 113formed in the adjacent face oftl1e"( .-urve(l 'ine 'nber ofthe videcl with a suitableprojectionby means of which it may be. turnecl'jto"positihn its sturl 13 in alin'ement with any selected socket 11 and by this means saigl arm or pointer can be held stz'itionary in any ad- 'justerl position. The sockets 11 are suitably spaced and arranged to conform to' line space distances on the platen tecrl ratchet 12 aml the gearing intermediate of the platen and pointer 8 is so propm-tioned that when the platen and pointer are turning together the latter will travel only onequarter as tast as the platen, sothat a half revolution of the pointer about theaxis of the platen will correspond to twocomplete revolutions ot' the platen.

Normally the parts will occupy' the position shown in Fig. 2 in which the pointer 8 resting upon an abutment or stud 15 secured to and projecting laterallyfrom the A tei-tererl with. the frictional engagement be tween the gears 5, 6 permitting; the former to rotate about the stud *Z- while the pointer 8 remains stationhry. If, however, the platen is turned backward. or in a reverse (llltPiLlOll, the pointer-will he'car'rieil away From the abutment 15 by the engagement of the pinion (i with the curved. track. a

In using the attachment fol-condensed billing the operator will, of course, first de shall be separated byja space equal to three line spaces the operator will position the armor pointer 14 in engagement with the proper socket of thevbracket 9.. After the rst bill has been written and withdrawn from the machine the platen will be turned backward until the pointer 8 comes into alinement with the pointer 14 or the. parts have the relative position shown in Fig. 3.?

The second bill will then be inserted in the machine and the platen turned forward until the pointer 8 is again bearing upon its abutment 15 when the second bill Wlll bewritten line.

in correct position to receive the first seated until the sales sheet is properly r as lled.

It will be seen that the pointer 8 is so connected'with the platen that it will move backward and-when said pointer is bearing upon the abutment 15 no appreciable check or obstruction to forward feeding of the platen is offered. The slight frictional'engagement between the disks or gears 5 and 6 is not appreciable so that the practically free and unlimitedro'tationof the either direction is-not interfered with.

Preferably a second abutment 16 posik the pointer 8 is turned. about the platen shaft until it rests upon the abutment 16 and the parts are then operated-asfollows: The first sheet to be Written is inserted in i the usual manner and the platen turned forward until the proper line is in writing position. The pointer 14 is then adjusted so that it is in alinement with the pointer 8. After the name and address have been Written the sheet is withdrawn, being pulled out backward if long enough, without releasing the paper feed rollers. Such backward turning of the platen will move the pointer 8 to a position of rest against the abutment 16 and when a subsequent sheet is inserted the operator turns the platen forward until the pointers 8 and 14 are in ,alinement, which will insure the proper positioning for re- This operation will be re.-'-
